Recommended holders for thread mills: HPC PRECISION CLAMPING CHUCKS Guhring s precision clamping chucks offer extremely high clamping forces while maintaining extremely tight concentricity tolerances, making it an ideal solution for milling operations, as well as drilling and reaming applications. It excels in both heavy-duty and high-speed machining applications. The special clamping sleeve is clamped via a worm gear, which transfers the optimal clamping force onto the tool shank. This creates clamping forces of > 200 Nm for 12 mm shank diameters and > 300 Nm for 16 mm shank diameters. New: Now available with PinLock Pull-out Protection!

Thread production with thread milling cutters and their advantages Thread milling is like thread cutting in that it is a chip forming production process. A major benefit of thread milling is the size of the thread to be produced, as the cost of taps in large dimensions can question the economic efficiency of the production process. Furthermore, with larger diameters thread cutting requires more power from the machine tool. The possibility of machining materials with a higher tensile strength or hardness can also be a decisive factor in choosing thread milling. With conventional thread cutting the thread is produced from the image of the tool profile, conditional on the chamfer lead for the workpiece. In contrast, with thread milling the thread is produced via a series of cutting paths by the milling cutter, whereby the pitch is generated by the machine. The thread mill makes numerous passes through the axis section of a thread during a spiral motion in axial tool-workpiece direction and thereby interpolates the contour of the thread. Technical Information With thread milling, an identical tool geometry can be applied for a multitude of materials. This considerably limits the multiplicity of tools required. In contrast to thread cutting, thread milling produces a complete thread which is virtually the total length of the applied tool. Comparison of tool design between taps/thread milling cutters In contrast to a tap, which basically consists of a single spiral shaped tooth, the series of teeth of a thread milling cutter do not form a spiral but are configured without pitch. This fundamental difference in tool design is attributed to the different processes which have already been described in an earlier chapter. P Tap The pitch P is produced by the tap/fluteless tap. A major factor is that cutting speeds and feed rates can be chosen independently of each other. Chip formation and tool loading can be considerably influenced via these setting parameters. A feature of the process is the formation of short, comma shaped chips in contrast to thread cutting. T Milling cutter The pitch P is produced by CNC control circular program) To detach the chips, the direction of rotation of the machine spindle does not need to be reversed. The tools applied have a thread profile without pitch. Initially, the thread milling cutter is lowered along the hole axis to the required thread depth. In the approach cycle the thread milling cutter is plunged to the nominal diameter of the thread. Dimensions and cutting section measurements Apart from the thread pitch of the tool, the design of a thread milling cutter is principally very similar to that of a tap. Thread milling cutters are also characterized by dimensions and the size of the cutting section. The thread length l 2 and the total length are also part of the dimensions. Technical The thread is produced by a 360º circular interpolation. Finally, in the exit cycle the thread milling cutter is radially returned to the hole axis and then axially withdrawn from the thread. A thread milling cutter can produce threads of varying diameters (or tolerances) with the same pitch. Right- or left-handed threads can be produced with the one tool. As thread milling produces only short chips, chip evacuation does not cause any problems. The different design forms incorporate milling cutters with or without collar as well as with or without countersinking chamfer. The cutting section sizes of a thread milling cutter consist of the flute length l 4, the flute profile, the tooth with Z b and the relief S. As with a tap, the flute length also incorporates the run-out of the flutes. They do not have to be as large as the flutes of a tap, as this machining process produces smaller chips. The chips do not remain in the flutes during the process and do therefore not restrict further chip development. The width of the tooth is therefore larger than with taps. The relief grinding helps to create the clearance angle required for milling cutters. 30

Technical Information Thread milling process and technology Machining combinations (reverse rotation/synchr. milling) As the thread milling cutters are designed for right hand cutting, the direction of rotation is generally clockwise. By altering the axial direction of feed, reverse rotation or synchronous milling, all thread combinations can be produced. The application conditions, such as blind or through hole, horizontal or vertical machining methods as well as the type of lubrication and chip removal determine the correct choice of milling procedure. For thread milling, synchronous milling should be applied whenever possible, in order to achieve lower cutting forces, improved chip formation, a better tool life and surface quality. Synchronous milling can be identified when the cutting edge emerges with chip thickness h = 0. reverse rotation milling synchronous milling Interference and feed ratio If the milling cutter diameter to the nominal thread diameter ratio of 70 is adhered to, a profile distortion, irrespective of the profile depth of the thread, should not occur. This factor is well proven. This drawing illustrates that the diameter of the thread milling cutter and the profile depth determine the pressure angle to the thread diameter. The feed at the cutting edge of the thread milling cutter is calculated by the cutting speed revolutions) and the feed rate per tooth. With linear movement, the feed rate at the cutting edge is identical to that at the tool center. However, the helical interpolation follows the path of a circle in the plane. As the machine tool always calculates to the tool center, a command must be programmed for converting the cutting speed (contour related program). If such a command does not exist or the central point is programmed, the feed rate must be first converted. Synchronous thread milling can be identified when the cutting edge emerges with a chip thickness h=0 h=0 h=m A The interactive control at the control panel always indicates the speed at the center point of the tool. When running with no load this is simple to check. If disregarded, the milling cutter runs at a speed many times faster than the feed which generally leads to tool breakages. pressure angle of thread milling cutter nom.

Thread milling cutter entry cycles Technical Information Thread milling process and technology Linear plunging With linear plunging of the thread milling cutter into the material, a very large angle of contact is created at the milling cutter which leads to long chips and a high loading on the tool. This is particularly the case when the difference in diameter between the hole size and the milling cutter is small. In addition, this method produces a small delay mark. This method is not suitable for accurate and small threads. Helical interpolation (cyl. thread) Helical interpolation is the overlaying of circular and linear movement. Different threads can be produced by the form of overlaying the direction of pitch and the direction of rotation of the circular movement. d 2 1 development of helical line 4 5 3 2 helix angle pitch p helix line circumference = π x d 90 quarter circle entry cycle A 90 entry cycle with a small difference in diameter between the tool and the thread removes a large part of chip volume during the linear section of the entry cycle. This method is therefore only recommended for relatively large differences in diameter between hole size and thread milling cutter (thread milling cutter TMU). The advantage using this entry method lies in the simple programming and the relatively short entry path. Helical interpolation (conical thread) In order to produce a perfectly round thread with a NPT thread milling cutter, it is necessary to take into account the pitch when NC-progamming. In contrast to cylindrical threads, the machining path is not a 360º circle but four segments of a circle. With every one of the four segments the taper is corrected inwards. d 2 1 1. circle segment pitch p 2. circle segment 3. circle segment 4. circle segment Technical 180 semicircle entry cycle With a 180 entry cycle, the loading on the tool is the lowest when plunging, as the angle of contact is relatively small during the complete entry cycle. This method requires a little more sophistication in programming but has shown to be the most costefficient when thread milling with the TM, TMC and DTMC thread milling cutter. d 2 2 32
